Speed-Vortex
If you don't need a fully race spec shoe but still require a shoe that can put up with a hell of a lot then the Speed-Vortex will be just what the doctor ordered. The Speed-Vortex is only pipped to the top of Diadora's road shoe range by the Vortex Pro, the only difference being a slightly heavier sole (10 grams across the pair) and the use of only one BOA system instead of the two that are on the Vortex Pro. The Speed-Vortex features the same upper and shoe internals which means that this is still a tip top performer for the serious rider, club rider and sportive expert.

The translation of Diadora means "to share gifts and honours" and originates from the Greek language. True to word, sharing all successes, combined with a sense of teamwork in the practice of sport at all levels and with a competitive streak that is always respectful of team-mates and opponents are some of the essential principles of Diadora.
This romantic and highly principled word, Diadora, is accompanied by a symbol, an ornament, which represents the origins of the company, which are rooted in a craftsman’s laboratory fabricating shoes since 1948. It’s not a flash or the tip of an arrow, as it may seem, it’s more appropriately the stylized version of an open upper: the very main element to make a shoe, whether for sport, leisure or work.

Diadora have been a pioneering brand since their birth in 1948 and to this day they continue to lead the way in top of the range cycling footwear.
